Proterozoic Orogens of India: A Critical Window to Gondwana provides a unique opportunity to understand a cross-section of the well-exposed and best-studied part of Earth’s crust and the processes of continental collision. It covers pulses of reworking processes and their impact on magmatism, metamorphism and deformational history of Proterozoic orogens vis-à-vis the supercontinental formation. The details of structural architecture, crustal blocks, shear zone systems, magmatism, metamorphism, geochemical and isotopic signatures, mineralization and tectonic models of all the Proterozoic orogens of India are discussed along with excellent illustrations reflecting the field-based, multi-scale structural and geological data sets. The spatial distribution, geometry, kinematics and transpressional strain of the shear zone systems (mostly suture zones), which are critical to all conceptual models dealing with tectono-metamorphic history of Proterozoic orogens of India, are also covered. The book summarizes and integrates the state-of -the art understanding of the structural architecture, lithological assemblages, petrological, geochemical, geochronological and geophysical aspects of the Proterozoic orogens of India. Includes a much needed state-of-the-art tectonic summary of the voluminous data that has emerged from the Protrozoic orogens of India in the last 2-3 decades Authored by a well-established expert with more than 30 years of experience in the field based, multi-scale structural geological studies of the ancient orogens of India Covers up-to-date reviews and models of Proterozoic orogens developed in the Indian shield over the past 2.5 billion years of Earth history

Atlas of Deformed and Metamorphosed Rocks from Proterozoic Orogens is a richly illustrated reference book featuring 400 full-color images of varied rock compositions, each with a concise description providing location, lithology, structural fabric, possible deformational history, metamorphic features, and other important geological information. Its relevance and significance in understanding the geological and tectonic history of the region is highlighted by providing relevant key references. The high-grade rocks included in the Atlas are mostly from the regions of Proterozoic orogenic belts. However, some of the regions in these orogenic belts are often covered by sediments, glacial deposits or vegetation, and therefore, inaccessible for scientific research. Atlas of Deformed and Metamorphosed Rocks from Proterozoic Orogens provides a range of lithologies and associated structural features that are captured from well-exposed sections of Proterozoic orogenic belts of India, Sri Lanka, Madagascar, Western Australia, Southern Africa, the Arabian Shield, and Antarctica. The Atlas provides an important source of information and reading for a broad range of earth scientists, graduate and undergraduate students, researchers, academicians and other professionals. This will also be useful for specialists in structural geology, petrology, geochemistry, geochronology, isotope studies, exploration geology, economic geology, and geophysics. Features 400 full-color photographs representing typical lithologies and associated structural and metamorphic features from different Proterozoic orogens Includes line drawings of the photographs for clarity and better understanding Presents regional geologic maps from Proterozoic orogens worldwide
This book surveys the history of the Earth and the nature of the processes that controlled its history. Integrating information from many fields, the book focuses on fundamental processes, the geological record, historical topics, and specific areas such as the development of modern ocean basins and the nature of cratonic sedimentary cover sequences.
